BMW R1234yf Air Conditioning

BMW R1234yf Air Conditioning

Vehicle air conditioning is now a very specialist field.

Various rules and regulations have now been imposed for correct handling of R1234yf (the gas inside your aircon system system). All of our aircon technicians are F-Gas trained and running the latest Bosch automatic AC equipment.

All electric vehicle use this R1234yf gas as it is non conductive.

Some owners try and cut corners with air con maintenance and use either a fast fit centre with a special offer or consider DIY air con refill kits that have suddenly sprung onto the market. Sadly they are too good to be true and are a total waste of your time and money. Although both options look like a money saver from the outset at around £50.00 you need to ask yourself some questions…

Where has the gas gone in the first place?

Obviously there maybe a leak on the system, if there is a leak then obviously we will report and advise rather than letting your expensive gas off into the atmosphere.

As time passes air con gas can disperse leading to an inefficient air con system.

If the system is low on gas, how will you know how much to put it?

Later BMW’s will not even attempt to turn the compressor over if the vehicle detects the wrong amount of gas in the system.

If your air con system has stopped working then it is beneficial to deal with the issue ASAP. If for an example a seal has gone which has allowed the gas to expel or a stone has gone through your condenser, the internals of the AC system is open to the atmosphere. An open system can take on moisture which is detrimental to all of the AC components and will lead to further costly repairs.

What we do when we service an air con system:

Full drain down of old air con gas.

Full vacuum test of air con system to identify any possible leaks, this also aids removing any moisture in the system.

If the vacuum test fails due to a leak in the system we then test the system for leaks with nitrogen free oxygen.

If no leaks are identified, the air con system is then refilled with the correct amount of R1234yf refrigerant gas.

New PAG oil is injected into the system. This step is often missed, however vital for long term maintenance.

Air con UV dye is injected into system (this aids detection of future leaks).

A full air con service report is printed for your service history stating R1234yf recovered from the system, status of vacuum test, quantity of PAG oil refilled, quantity of UV dye refilled and finally quantity of R1234yf refilled into the system.

We recommend two levels of regular servicing for your AC system (every two years).
